Imiterere yimbere mu gihugu hamwe niterambere ryinganda zubushinwa PVC

PVC ni kimwe mu bikoresho bitanu byitwa resin, bifite ibimenyetso byiza nka acide na alkali birwanya, kwambara birwanya, kutagira umuriro, no kubika. Kugeza ubu, ibaye icya kabiri mu bicuruzwa bya pulasitiki ku isi nyuma ya polyethylene.
1.Ubushobozi bwo kubyaza umusaruro umusaruro nibisohoka bya PVC
Igikorwa cyo kubyaza umusaruro PVC kirimo inzira ebyiri: uburyo bwa calcium karbide nuburyo bwa Ethylene, itandukaniro nyamukuru nuburyo bwo gutegura vinyl chloride monomer.
Urebye ku musaruro mu myaka yashize, umusaruro wa PVC wagaragaje kwiyongera uko umwaka utashye, kandi umusaruro w’inganda zose winjiye mu ntera ishimishije. Isoko ryamasoko ryagiye ryiyongera buhoro buhoro, kandi umusaruro wiyongereye buhoro buhoro. Dukurikije imibare yaturutse mu Bushinwa Chloroalkali Network, igipimo rusange cy’inganda za PVC mu Bushinwa cyagumye hejuru ya 50% mu myaka yashize.
2.Iterambere ryiterambere ryinganda za PVC
(1) Gushimangira kubaka ibikoresho byo guhuza inganda
Kuva mu 2007, igihugu cyashyizeho urutonde rwamabwiriza atanga amabwiriza arambuye yiterambere ryinganda za PVC. Muri icyo gihe, ishishikariza kubaka ibikoresho bifasha kariside ya calcium na chlor alkali ikora inganda, kandi bigashimangira kubaka ibikoresho byo guhuza inganda. Ku buyobozi bwa politiki y’igihugu iriho, ishyirwaho ry’ibikoresho byo guhuza inganda byahindutse inzira byanze bikunze mu turere two hagati n’iburengerazuba bw’Ubushinwa, bikungahaye ku makara, mu birombe by’umunyu, no ku mutungo w’amabuye. Muruhare rwibikoresho byahujwe, mu kwishingikiriza kumitungo ikungahaye hamwe nibyiza bihuye, ibiciro byumusaruro birashobora kugenzurwa neza kandi nibicuruzwa bitandukanye bishobora kongera gukoreshwa, Kongera ubushobozi bwisoko ryisoko nubushobozi bwo kubaho kwikigo.
(2) Uburyo butandukanye bwo gukora
Muri iki gihe iterambere ry’inganda zo mu gihugu PVC, hibandwa ku buryo butandukanye bwo gutunganya ibikoresho by’ibicuruzwa bigenda byiyongera, ibyo bigatuma ibyo basabwa ku rwego rw’ikoranabuhanga bigenda byiyongera. Inzira yo gutandukanya inzira ntishobora guhagarara. Hamwe niterambere ryiterambere ryimikorere ya PVC yimbere mu gihugu, ibigo bigomba gukoresha buhoro buhoro uburyo bushya bwo gukora mugihe hagumijwe kariside yambere ya calcium. Muri icyo gihe, tekinoroji ya PVC ya polymerisation nayo izanozwa ku buryo bugaragara, cyane cyane mu bijyanye n’ubushobozi bwo gukora reaction ya polymerisation. Byongeye kandi, birakenewe kandi kumenyekanisha byimazeyo tekinoloji y’umusaruro w’amahanga yateye imbere no kuyiteza imbere buhoro buhoro kugira ngo ubukungu bwiyongere mu bukungu.
